bp compression and tygon ?

[jtf2]

is this the barb to use
Bitspower Matt Black 7/16in. Compression Fittings for 5/8in. OD Tubing # BP-MBCPF-CC6

with this tubing

Tygon R3400 7/16in. ID 9/16in. OD Laboratory Tubing # AAE00032

it looks to be so,but the fitting says 5\8od,and yet the tubing is 9\16 od
thanks

You want the tubing and the fitting to match perfectly. If the barb is a 7/16ID 5/8OD then make sure you have 7/16ID 5/8OD tubing.

The tubing will fit the barb but when tightning the compression fitting to the barb the tube's thickness will be thinner than recommended and can cause leaks.

I have no experience with the two, I am just going from logic.

If it works and you can actually get the collar over the tubing in the first place, you'll basically be trying to crank the comp down on tubing that's too wide, which usually makes for a pinch point above the barb, rather than on it (like it's supposed to be). Not recommended, in my books. If someone's specifically tried the combination and it works, that's fine. But my own experience with Tygon/BP comps says that there isn't a whole lot of clearance to be had. If you do, I'd definitely give it a good, long leak-test before letting anything power up.

so this then would be the proper tubing
Tygon R-3603 7/16" ID 5/8" OD Chemical Tubing - AAC00033
but now i need to see if anyone sells that in black?

[vohiep84]

Yep those work.

Just curious why those dimensions?

i find that they are just easier to work with than the 1\2id 3\4 od tubing,and in the end the flow loss is negligible.
i see that primochill sells that size tubing in black,now i just have to hunt down who has it!!
